I see a bunch of guesses based on the series of Tweets, but nothing definitive. And as I am waiting on my order I placed in November, and had a 14-50 plug installed in reliance on the list of included equipment at my reserved price, as that rate of charging is all I will need, I would like to know.
Whether this is a good decision for Tesla moving forward is irrelevant to this thread, as the thread is for people who have already ordered, and were counting on using the included charger at home, because it worked for them.
Any posts on why we should have chosen a Tesla wall charger, or tales of how you never used your Mobile charger, are unhelpful and unwelcome. This thread is just to confirm what is going on with already existing orders placed before this announced change.
